We continue our series of papers on open cluster distances wi th a critical assessment of the accuracy of mainsequence fitting using isochrones that employ empirical cor re tions to the color-temperature relations. We use four nearby open clusters with multicolor photometry and ac curate metallicities and present a new metallicity for Praesepe ([Fe /H] = +0… CONTINUE READING
